Question

Which is the value of X in the equation 8x-2y=48 when y=4

Answer 1

Substituting 4 in place of Y would make the equation 8x-2(4)=48. The value of X is 7.

Answer 2

8x - 2(4) = 48 Replace y with 4

8x -8 = 48 Simplify

8x = 56 Add 8 to both sides to cancel the 8 on the left side

x = 7 Divide 56 with 8 to isolate x
